show ccm-manager

If your MGCP network includes Cisco CallManager, use this command to verify the active and redundant configured Cisco CallManager servers. This command also indicates if the gateway is currently registered with Cisco CallManager.

Note:

The following show ccm-manager command output was captured in a separated environment.

show mgcp

Use this command to verify the status of the router's MGCP parameters. You should see the IP address of the server that you are using (172.16.1.252 in this case.) All of the other parameters were left at their default behavior in this configuration.

MGCP call-agent

The address of the call agent specified in the mgcp command.

MGCP block-newcalls enabled

The state of the mgcp block-newcalls command.

MGCP request timeout

The setting for the mgcp request timeout command.

MGCP request retries

The setting for the mgcp request retries command.

MGCP gateway port

The UDP port specification.

MGCP maximum waiting delay

The setting for the mgcp max-waiting-delay command.

MGCP restart delay

The setting for the mgcp restart-delay command.

MGCP VAD

The setting for the mgcp vad command.

MGCP codec type

The packages supported in this session.

show mgcp endpoint

Use this command to show the voice ports (endpoints) that are under MGCP control in the router. This command verifies which voice ports have been bound to the MGCP application. This is related to the application mgcp command and the port commands that were entered when configuring the POTS dial peer.

show mgcp connection

Use this command to display any active MGCP connections. The endpoint in this example is Slot1/Module 1/Port 0. This corresponds to the MGCP Member Configuration identifier in Cisco CallManager. This tells you which port on the router is the endpoint in the call.

Table: Explanation of Fields in the show mgcp connection Command

The endpoint for each call shown in the digital endpoint naming convention of slot number (S0) and digital line (DS1-0) number (1).

Call_ID(C)

The MGCP call ID send by the call agent, the internal Call Control Application Programming Interface (CCAPI) call ID for this endpoint, and the peer call legs CCAPI call ID.

(CCAPI is an API to provide call control facilities to applications.)

Conn_ID(I)

The connection ID generated by the gateway and sent in the ACK message.

(P)ort

The ports used for this connection. The first port is the local UDP port. The second port is the remote UDP port.

(M)ode

The call mode, where:

0-Indicates an invalid value for mode.

1-Indicates the gateway should only send packets.

2-Indicates the gateway should only receive packets.

3-Indicates the gateway can send and receive packets.

4-Indicates the gateway should neither send nor receive packets.

5-Indicates the gateway should place the circuit in loopback mode.

6-Indicates the gateway should place the circuit in test mode.

7-Indicates the gateway should use the circuit for network access for data.

8-Indicates the gateway should place the connection in network loopback mode.

9-Indicates the gateway should place the connection in network continuity test mode.

10-Indicates the gateway should place the connection in conference mode.

All other values are used for internal debugging.

(S)tate

The call state. The values are used for internal debugging purposes.

(C)odec

The codec identifier. The values are used for internal debugging purposes.

(E)vent [SIFL]

Used for internal debugging.

(R)esult [EA]

Used for internal debugging.

Other debug mgcp Commands

Use debug mgcp {all | error | events | packets | parser} when you are experiencing problems that you believe are not related to configuration errors or hardware problems. It is recommended that you keep an example of each debug command from a working configuration to use as a baseline for comparison when you are experiencing problems.
